I was thinking about the massive projects that the world has seen, like the Pyramids, great Dams, Bridges, Skyscrapers and Railways, or well-designed and -architected cities in general, and wondering: Are these things we marvel at, built on great inequities? Inequities that people of certain demographics cannot even imagine (thinking about myself as a white, male, middle-class American).
It's not comfortable to think about, but would such marvels even exist if there were not the exploited and the exploiters? Can this said to have been even necessary for technical progress?
Food for thought.
